According to the specifications the capacitance may vary with voltage, so instead I would like to measure the current and prefer the input voltage to be indepent of the transfer
According to our MNA equation I can garauntee that the input voltage is independent of the output by setting $A_T=0$ and $B_T=0$.
According to our MNA equation I can garauntee that the output current is independent of the load impedance by setting $D_T$=0.
